9.3 PT113PN - Profinet
The PT113PN instruments are state-of-the-art strain gage load cell signal digitisers with a Profinet
interface. This instrument is used for any type of weighing processes and force measurement including
tank and silo weighing, dynamic weighing, check weighing, filling, tension /compression force
measurement etc.
A sample GSDML file is available supplied together with the instrument to aid in setup.
For connections refer to 4.2.1 and the table below. For front panel annunciator explanation refer to
5.1.2.4 and 5.1.2.1.
Profibus-DP interface
This interface uses Profibus-DPV1
Usage
Interfacing with a PC or PLC
Data formats
Profinet
Baud rate
The Ethernet interface operates at 100Mbit, full
duplex, as required by Profinet.
Warning:
Connect the shield to the reference ground or shield pin of the power connector.
Warning:
Disconnect AzComT PC software after configuration for Profinet interfacing to function
correctly.
9.3.1.1 Programming and Calibration
PT113PB instruments are programmed and calibrated with AzComT. Analogue digitiser parameter
values are very important for better weighing performance. Please refer to 6.3.1.
9.3.1.2 Profinet Setup
Profinet set up is performed with AzComT software as described in section 6.3.4.3.
Select Gateway tab after connecting AzComT to the instrument.
Refer to the previous page (9.2.1.3) under Profibus for PLC configuration.
